How to Check Your Transmission Fluid

SAN JOSE — Most drivers know to keep an eye on their engine oil, but not everyone is so diligent about checking their transmission fluid. However, due to the important role a transmission plays in vehicle operation (as well as the substantial expense of repairing it), you should make a point of checking yours regularly.

Checking your transmission fluid involves the same steps as checking your engine oil: Just pull out the red dipstick (as opposed to the yellow one for engine oil) and inspect it. Most importantly, check the fluid’s integrity. Transmission fluid should have a clean, pink color and a semi-sweet aroma. If it looks dirty or smells burnt, you’re past due for a change, in which case you should schedule a service appointment with your auto technician as soon as possible.

In addition to independently checking your transmission fluid, have your transmission professionally serviced at regular intervals. Ideally, you should get a complete fluid and filter change every 40,000 miles. This simple step will add years to your transmission’s life and prevent costly damage.
